Embodiment
As discussed above, there are the Software tool and the storehouse that make it possible to show three-dimensional (3D) image.For example, OpenGL is the industrial standard graphical application DLL (dynamic link library) (API) that is used for two dimension (2D) and three-dimensional (3D) graphical application.In general, OpenGL API handles the graph data of the object that will play up that expression receives from host application (for example computer-aided design (CAD) software, video-game, 3D user interface etc.), and on display device the render graphics object so that watch.The graph data of each Drawing Object that will play up comprises the array of 3D coordinate and associated data (being commonly referred to the summit).The Drawing Object vertex representation is 4 element homogeneous vectors [x, y, z, w], and wherein x, y and z are the apex coordinates in the 3d space, and w is one (1).When receiving the Drawing Object summit of Drawing Object, OpenGL API conversion Drawing Object summit, and come the constructing graphic primitive by many block graphicses object summit being concentrated in together to form point, line, triangle and polygon.Then, the graphic primitive of being constructed being played up bitmap shows on display device being used for.
In its current form, OpenGL API provides the support to the conventional stereo display, wherein for each picture frame that will show, the left and right sides version that produces image by specialized hardware is to be used for independently presenting to every eyes of observer, and wherein each version has independently advantage with respect to identical 3d space.Be used for the left image of picture frame can be adopted different forms according to the type of three-dimensional display with the hardware that right image is presented to the observer.For example, two eyes that available two little wear-type display floaters are presented to the observer with the image on the image on the left side and the right, wherein each display floater presents the respective image in the image on the image on the left side and the right.Perhaps, can on single monitor, present the image on the left side and the image on the right according to the mode that replaces.In this case, use special (polarisation) glasses, during the image that shows the left side, block right eye, and during the image that shows the right, block left eye.To recognize, no matter be used for to the observer present the image on the left side of picture frame and the right image hardware how, all produce and show the complete of each picture frame and left and right sides image independently.Unfortunately, the process of playing up two full releases of each image for each picture frame can cause that every sample thing will draw twice, and this is on calculating and spend very high in the storage.
Forward Figure 1A and 1B now to, the block diagram of the 3D graphics system of the prior art that is suitable for playing up the 3D graph image is shown.With reference to Figure 1A, graphics system 100A comprises application program 102 such as video-game, is used for providing the 3D shape library so that play up OpenGL application programming interfaces (API) 106, video driver 108, viewing hardware 110 (as Graphics Processing Unit (GPU)) and left and right sides display floater 112 and 114 of 3D graph image to application program 102, and wherein each display floater aligns with observer's corresponding eyes.Video driver 108 provides the interface between OpenGL API 106 and the viewing hardware 110 to connect (interfacing).By using application program 102 and OpenGLAPI, viewing hardware 110 is with two the different versions of 3D graph image format conversion (format) with the generation identical image, wherein for each picture frame that will show, each image (that is left and right sides image) has different advantages with respect to identical 3d space.Then, with the left and right sides image applications that produced to corresponding display panel 112 and 114 and two eyes of presenting to the observer, so that the observer perceives 3D rendering.Figure 1B illustrates another the 3D graphics system 100B similar to the 3D graphics system 100A shown in Figure 1A.In this embodiment, except application program 102, OpenGL API 106, video driver 108, viewing hardware 110 and left and right sides display floater 112 and 114, graphics system 100B also comprises private library module 118, private library module 118 provides extra 3D shape library to be used to create complicated day by day graphic primitive, plays up thereby make it possible to produce meticulousr 3D rendering.
Though above graphics system 100A and 100B are described as comprising respectively left and right sides display floater 112 and 114, as previously mentioned, graphics system 100A and 100B can alternatively comprise single display floater.In this case, display floater shows the complete left and right sides image of each picture frame in the mode that replaces.The polaroid glasses that the observer wore block observer's left eye during showing right image, and block observer's right eye during showing left image, so that the observer perceives 3D rendering.
To recognize that no matter adopt which type of viewing hardware, for each picture frame that will show, graphics system 100A and 100B produce and show two complete versions of same image.This makes clean processing and storage demand increase.
With reference now to Fig. 2,, graphics system 200 is shown, and graphics system 200 comprises application program 202 such as video-game, is used for providing the 3D shape library so that play up OpenGL application programming interfaces (API) 204, video driver 206, viewing hardware 208 (as GPU) and liquid crystal display (LCD) panel 210 of 3D graph image to application program 202.Video driver 206 provides the interface between OpenGL API 204 and the viewing hardware 208 to connect.By using application program 202 and OpenGL API 204, viewing hardware 208 is used for 3D graph image format conversion to present by LCD panel 210 to produce the stereogram picture frame.
Fig. 3 illustrates the assembly of viewing hardware 208 better.As seen from the figure, viewing hardware 208 comprises hardware rasterizer (rasterizer) 304, pre-sheet unitization operational module 306 and back buffer device 308.If desired, rasterizer 304 is converted to sheet unit so that handle by pre-sheet unitization operational module 306 with graphic primitive.Each sheet unit (fragment) comprises color, texture, coordinate, the degree of depth and back buffer device positional value.306 pairs of sheet units that require to handle of pre-sheet unitization operational module carry out one or multinomial test and modification, include but not limited to stencil test, depth test and fusion.To not require that the sheet unit of processing and the sheet unit that handles through pre-sheet unitization operational module 306 are written to back buffer device 308 to form final bitmap, output to LCD panel 210 then.In this embodiment, back buffer device 308 comprises the rectangular array of the bit plane that is organized into a plurality of logic gate buffers.In order to reduce clean processing and storage demand, viewing hardware 208 only forms those pixels of the part of the stereogram picture frame that will see in the image of the rasterisation left and right sides, and this will hereinafter be described.
Fig. 4 illustrates the pixel map of LCD panel 210.In this embodiment, LCD panel 210 with establish by Sanyo Epson imaging
(SEID) Kai Fa LCD panel is similar.The pixel that the appointment of LCD panel 210 is seen with observer's right eye is with ' R ' mark, and the pixel that the appointment of LCD panel 210 is seen with observer's left eye is with ' L ' mark.Right eye and left eye pixel R and L are interweaved to form checkerboard pattern, and this is convenient to produce the 3D display effect from observer's angle.For this checkerboard pattern, in any given pixel column or pixel column of LCD panel 210,50 (50%) percent pixel is right eye pixel R, and 50 (50%) percent pixel is left eye pixel L.LCD panel 210 also comprises filter (filter) (not shown), and this filter comprises the barrier grid that covers the LCD panel pixels.This filter makes to have only from specific direction just can see light from each pixel of LCD panel 210.When the observer was in correct observation place with respect to LCD panel 210, left eye pixel L can only see with observer's left eye, and right eye pixel R can only see with observer's right eye.As a result, in such observation place, when LCD panel 210 presented the stereogram picture frame, because left eye is seen the image by the L shaped one-tenth of left eye pixel, and right eye was seen the image that is formed by right eye pixel R, so the observer sees two different editions of identical image.This allows to produce 3D rendering from observer's visual angle, and does not need to show two complete versions of identical image.
In general, in operating process, when graphics system 200 will show the stereogram picture frame, similar to the graphics system of prior art, application program 202 combine with OpenGL API 204 produce identical image about two single picture (monoscopic) versions, wherein each image has different advantages with respect to identical 3d space.For restricting data is handled, those pixels of the part of the stereogram picture frame that only in each image of rasterisation formation is presented on the LCD panel 210 and watches for the observer.As a result, because each image only is used for driving a half-pix of LCD panel 210, so abandon the half data in each image.Then, the pixel through rasterisation of viewing hardware 208 these two images of combination is used for showing to produce the stereogram picture frame.For example, as shown in Figure 5, the left image 410L of single picture and the right image 410R of single picture are shown, their combination backs produce single stereogram picture frame 410S to be used for demonstration.Embedded block (inset) 411L and 411R highlight four pixels in the lower left corner of image 410L and 410R respectively.Embedded block 411L comprises pixel 412L, 414L, 416L and 418L, and embedded block 411R comprises pixel 412R, 414R, 416R and 418R.Only pixel 412L and the 418L of rasterisation (rasterize) embedded block 411L, and only pixel 414R and the 416R of rasterisation embedded block 411R.Abandon pixel 414L, 416L, 412R and 418R.The pixel of the process rasterisation of combination image 410L and 410R is to produce stereogram picture frame 410S.In stereogram picture frame 410S, embedded block 411S comprises pixel 412L, 414R, 416R and 418L.To recognize that the chessboard that stereogram picture frame 410S has from the pixel of the process rasterisation of left and right sides image 410L and 410R distributes.
When graphics system 200 will produce the stereogram picture frame when being used to be presented on the LCD panel 210, OpenGL API 204 conversion form the Drawing Object summit of the Drawing Object of complete left and right sides image, and construct the graphic primitive of left and right sides image through the Drawing Object summit of conversion by gathering many groups.Because only the subclass of each left and right sides image form will the stereoscopic images displayed frame a part, so in order to reduce data processing, but only will form graphic primitive and the observed person sees when demonstration stereogram picture frame pixel rendering becomes bitmap.Fig. 6 illustrates the step that graphics system 200 is carried out better during the render graphics primitive.
At first, behind the graphic primitive of having constructed left and right sides image (left and right images), select one of them graphic primitive (step 602).In step 604, determine to form the pixel tabulation of selected graphic primitive.Tabulate one of the multiple algorithm of available execution ' bounding box (bounding box) ' routine of pixel produces.The use of bounding box routine has avoided will handling in order to determine the shared pixel of selected graphic primitive each pixel in the image.In case produced the pixel tabulation, just first pixel in the selective listing, and do check to determine whether this pixel is positioned at the position (step 606) that the observer can see when the demonstration stereogram picture frame.For example, if selected graphic primitive forms the part of left image, then check selected pixel with the position of determining it whether corresponding to one of left eye pixel L of LCD panel 210.If selected graphic primitive forms the part of right image, then check selected pixel with the position of determining it whether corresponding to one of right eye pixel R of LCD panel 210.In step 606,, then abandon selected pixel if selected pixel is positioned at the position that can not form a part that will the stereoscopic images displayed frame.Then, do check to determine that whether selected pixel is last pixel (step 608) in the tabulation.If determining selected pixel is last pixel in the tabulation, think that then the render process of selected graphic primitive is finished, select next graphic primitive (step 602) this moment.If selected pixel is not last pixel in the tabulation, the next pixel in step 610 selective listing then, and process turns back to step 606.
In step 606, if selected pixel is positioned at the position of the part that formation will the stereoscopic images displayed frame, then by the rasterizer selected pixels of 304 rasterisations (step 612).Then, if desired, unit carries out pre-sheet unitization operation (step 614) to the gained sheet, is written to back buffer device 308 (step 616) then.After step 616, process proceeds to step 608, in step 608, does check to determine that whether selected pixel is last pixel in the pixel tabulation.If determining selected pixel is last pixel in the tabulation, think that then the render process of selected graphic primitive is finished, select next graphic primitive (step 602) this moment.If not, the next pixel in step 610 selective listing then, and process rotates back into step 606.To recognize, only those pixels that when on LCD panel 210, showing the stereogram picture frame, can see in the rasterized pattern primitive.Certainly like this, processing and storage demand have been reduced.
Although above rasterizer 304 being described as is hardware rasterizer in the viewing hardware 208, rasterizer 304 can be used as the software module that is arranged in video driver 206 or OpenGL API 204 and realizes.
Forward Fig. 7 now to, another graphics system 720 that is used for the rasterisation 3D rendering is shown.In this embodiment, graphics system 720 pixel of utilizing the OpenGL3D shape library to come rasterisation to be associated according to the order that receives from application program with 3D rendering (as one or more graphic primitives).As shown in the figure, graphics system 720 comprises processing unit 722 (as CPU or GPU), random access memory (" RAM ") 724, nonvolatile memory 726, communication interface 728, viewing hardware 730, user interface 732 and the LCD panel 734 similar to LCD panel 210, and they all pass through local bus 736 communications.Processing unit 722 takes out (retrieve) with the rasterisation software application to RAM724 from nonvolatile memory 726, is used for being carried out by processing unit 722.The rasterisation software application is with the mode render graphics primitive similar to the mode shown in Fig. 6, and presents the gained bitmap on LCD panel 734.By user interface 732, the observer can select and will be sent to nonvolatile memory 726 through the 3D rendering of playing up, and perhaps is sent to one or more remote storage devices and/or remote display by communication interface 728.Nonvolatile memory 726 also can be stored the other software application that can be used to support other graphics process operations.
